For instance, the estimation of groundwater discharge in central and eastern European countries showed the average of estimated groundwater discharge (6 % of total water flow) is about 12 percent of the estimated evaporation [Zektser and Loaiciga, 1993]. This estimate is about the same order of uncertainty usually assigned to evaporation estimates.

Nov 25, 2014· Abstract. Limestone mining at Lanjiberna limestone and dolomite quarry has created positive as well negative impacts on ground water. With further deepening of the mine, drawdown trend (negative effect) is observed and at the same time ground water recharge of the order of 4,527.48 m 3 /day, through mine pits (positive impact) is noticed. The aquifer present in the area is unconfined and ...

Impact of quarry deepening on local groundwater users - SRK

The quarry depth of 78m as of 2007 caused a zone of drawdown in groundwater levels in the surrounding shale aquifer, extending ~5km to the east but a smaller distance to the west, because of good recharge from the mountainous sandstone aquifer located there. Current groundwater inflow is ~200m3/day, with an electrical conductivity of 260 to ...

Groundwater flow equation - Wikipedia

the groundwater is flowing slowly (Reynolds number less than unity), and; the hydraulic conductivity (K) is an isotropic scalar. Despite these large assumptions, the groundwater flow equation does a good job of representing the distribution of heads in aquifers due to a transient distribution of sources and sinks.

Also, the pumping test is often used to estimate radius of influence; it can trigger the inflow or radius of influence. Estimate of the radius of influence using analytical equation mainly independent of discharge/abstraction from the aquifer stands as a preferred choice for the prediction of radius of influence at the quarry/mine pit.
